Zennoposter freezes after a certain time

[Stroks]

Sometimes after 20 minutes and sometimes after 5 hours the script just stops working in the zennoposter. Threads are active and the browser look normal but they do not proceed after a certain point. All threads i used 5 for the projects, so i suppose this is not a thread specific problem but problem with ZP.

No errors in log at all. Log in zennoposter says nothing except this (which may not be related to the problem)

Another log at the time error happened:

I have a long list of around 3MB with 100k lines.I remove duplicates from the list in the template.

Never mind. It seems like i made an infinite loop in an C# block.

while (ind){
//in a case i didn't increase counter
if (counter = something) ind = false;
}
